Description
The OSG Threading Tap Metric A-Spiral Flute with a +0.1 oversize tolerance is a precision tapping tool designed for metric blind-hole threading. Built for right-hand applications, it delivers consistent M4 x 0.7 threads in confined spaces where an oversize fit is advantageous.
- Brand: OSG
- Tool Type: Metric threading tap
- Flute Style: A-Spiral flute for efficient chip evacuation
- Size & Pitch: M4 x 0.7
- Oversize Tolerance: +0.1
- Material: Powder metal for high strength and wear resistance
- Coating: TiCN coating to increase hardness and reduce friction
- Direction: Right-hand threading
- Application: Blind-hole tapping; DIN371 compliant
Designed to produce reliable, repeatable threads in metric blind holes, this tap minimizes the risk of stripping and reduces the need for rework. The TiCN coating enhances performance under high-speed machining, while the powder-metal substrate provides a durable balance of toughness and wear resistance. The spiral flute geometry promotes smooth chip flow, helping maintain cutting efficiency and preventing clogging in tight holes. This makes it a strong choice for automotive, electronics, and precision fabrication projects where accurate, consistent threads in tight spaces matter.
